A humble fixed price for mobile internet in over 120 countries is Google’s latest ambition that would allow users to save thousands of dollars on mobile phone operators’ packages.Project Fi, which is Google’s way of jumping in the middle of the great carrier race, has shared today that starting tomorrow, you can order a SIM for your data-only device. For subscribers connected to either the Sprint or T-Mobile network, when out of range, Project Fi offers three handsets – Nexus 6, Nexus 6P and Nexus 5X – to enable communication.

Once you’ve ordered and received a data-only SIM, just pop it into a compatible device, follow the instructions, and voila: instant wireless connectivity. Those who would like to join the early access program can request an invitation. “With this update, you can access cellular connection from tablets and other connected devices while on the go. This will dramatically change the price of wireless for travelers too: a flat rate of $10 per GB is a far cry from costly roaming plans mobile operators offer their clients.

Unlike the three handsets, which connected to the T-Mobile or Sprint network depending on which one was stronger at the moment, data-only devices use T-Mobile’s network only, in the absence of a Wi-Fi signal. Subscribers have been getting LEGO sets as a holiday gift, so it’s nice to see that Google is making the customer service for carriers space better.

According to commentators, the addition of tablet support was a sign of Google’s growing ambitions in the wireless business and reflected its push for change in the industry. Then, companies like Straight Talk, Boost Mobile, MetroPCS, Cricket Wireless, or Project Fi will lease access, then sell it to us at a discounted rate. Project Fi offered consumers who were looking for broader coverage for their tablets – say, away from home or a coffee shop with a Wi-Fi hotspot – a cheaper alternative to traditional cellular wireless plans.

You still need a modern Nexus phone to sign up for Project Fi in the first place, though, so this doesn’t do anything to expand the pool of users that are able to use Google’s competitively-priced service.
